S 424-026
CAUTION: THE ROUTING OF THE MULTI-CONDUCTOR SAFE-SIDE WIRE HARNESS IS
_______ CRITICAL FOR PROPER OPERATION AND INTRINSIC SAFETY OF THE FQIS. THE SAFE-SIDE HARNESSES ARE TO BE ROUTED WITH A MINIMUM 0.5 INCH (12.7 MILLIMETERS) CLEARANCE FROM OTHER AIRPLANE WIRING IN NON-PRESSURIZED AREAS. A MINIMUM OF A 0.25 INCH (6.35 MILLIMETERS) MUST BE MAINTAINED FROM OTHER AIRPLANE WIRING IN PRESSURIZED AREAS.
WIRE BUNDLE ROUTING AND INSTALLATION SHALL BE IN ACCORDANCE WITH SWPM SECTIONS 20-10-11 AND 20-10-12.
ALL WORK SHALL BE IN ACCORDANCE WITH THE SAFETY PRACTICES DESCRIBED IN SWPM 20-00-10.
